This tip shows how to get the keys generated for the rows added by an
INSERT statement.
Statement st=null;
PreparedStatement pst=null;
Connection conn=null;
ResultSet rs=null;
ResultSetMetaData rsmd=null;
...
try {
st= conn.createStatement();
}catch (SQLException e)
{System.out.println(e.getMessage());}
try {
pst= new conn.prepareStatement(INSERT INTO table_name (field1, field2, ...) VALUES]
(?, ?, ...),Statement.RETURN_GENERATED_KEYS);
pst.settype(1,val_1);
pst.settype(2,val_2);
...
pst.settype(n,val_n);
pst.executeUpdate();
rs =pst.getGeneratedKeys();
if (!rs.next())System.out.println(No keys!);
else
{
rsmd = rs.getMetaData();
while (rs.next())
{
for (int i = 1; i <= rsmd.getColumnCount(); i++)
{
String ch = rs.getString(i);
System.out.println("ch{" + i + "}:" + ch);
}
}
}
}catch (SQLException e)
{System.out.println(e.getMessage());}
